terial and in which the primary illuminating means is so disposedrelative thereto as to provide efficient conduction of light and,therefore,

high illumination with a minimum of light glare.

Another object of the invention is to provide a device, as indicated,particularly useful at night or in the dark, and wherein the messagesupporting means comprises efficiently arranged light conveying membershaving a minimum of light leakage and, consequently, minimum glare.

Another object of the invention is to provide a device of the characterindicated in which the message-supporting means comprises a pair ofangularly diverging light-conveying members and placing a light sourceat the apex or extended point of intersection of said members to obtainmaximum light for passage through said members with attending minimumglare.

My invention also has for its objects to provide such means that arepositive in operation, convenient in use, easily installed in a workingposition and easily disconnected therefrom, 'economical of manufacture,relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction 'and novelcombinations and arrangements of parts, which will more fully appear inthe course of the following description. However, the drawings merelyshow and the following description merely describes one embodiment ofthe present invention, which is given by way of illustration or exampleonly.

In the drawings, like reference characters designate similar parts inthe several views.

Fig. 1 is a front elevational view, partly broken, of a message deliverydevice embodying the present invention.

Fig. 2 is an enlarged sectional view, in the plane of Fig. 1, showingthe support frame construction.

Fig. 3 is a longitudinal sectional view through the center of Fig. 2.

Fig. 4 is an enlarged longitudinal sectional devices for holding an 1Claim. (01. 258-2) view through the handle and power source means of thedevice.

The message delivery device which is illustrated in the drawingcomprises, generally, a support frame 5, a message-carrying loop 6releasably mounted on the frame, a light source I, a power source 8 forthe latter, a connecting extension 9 between the frame 5 and the powersource 8, and a handle I 0.

As contemplated, the frame 5, essentially comprises three simpleelements-a pair of similar straight light-conveying rods, such as LuciteH, and a Lucite connecting fitting l2 mounting said rods to have anupward diverging included angle in the nature of a Y. Each rod II isprovided with a polished end face I3 nor mal to the rod axis, and with apreferably notched opposite end face 14 also normal to said axis.

The fitting I2 is formed with a pair of angularly related holes or seatsl5 receptive of the adjacent rod ends so that the end faces I3 are inedge contact and arranged at an obtuse angle with each other. secured intheir seats as by a transverse pin [6 passing through each rod andthrough the fitting l2.

The frame 5 further includes one or more snap clips ll. Two such clipsare shown and each comprises a flat spring member secured as by a rivetl8 and a screw l9 to the fitting l2 and formed with a resilient tongue20 which is upwardly directed.

The message-carrying loop 6 comprises an endless piece of string or wire2| to which a message bearing piece of paper 22 is tied. The loop isarranged to engage in the notched rod ends H, to extend across andbetween said ends and to be downwardly trained and caught by one of thesnap clips H. The loop 6 is thus arranged in triangular form and it willbe evident that by grasping the transverse extension of the loop or themessage 22 and exerting a light pull, the tongue 20 will flex to releasethe loop.

The light source 1 comprises a conventional lamp 23 and is located at oradjacent to the point of intersection of the axes of the rods ll so thatthe rod end faces l3 receive light directly from the lamp to be conveyedalong the length of the rods.

The lamp 23 is carried on an end of the connecting extension 9 and aseat 24 is provided in the fitting ii for said end, said seat beingextended to intersect the seats IE to form a chamber 25 in which thelamp is disposed.

The power source 8 consists of a conventional The rods Il may besuitably 3 dry cell battery 26 mounted in a tubular housing 21 andcontrolled by a switch 28 carried by the top of said housing 21.

The connecting extension 9 is formed of a tube 29 which carries one sideof the current from the battery 26 to the lamp 23, and a central spacedconductor 30 which forms the return path of current between the lamp andthe battery. The low voltage entailed obviates the need for insulatingthe tube 29. An outside source of power may be used. In that event thehousing 2'! and its contents may be omitted and a conventionaltwo-conductor cord passed up through extension 9 to a suitable lampsocket for the lamp 23.

The handle I0 comprises a tubular extension from the lower end of thehousing 21 and serves as a means for extending the device both up- WhileI have illustrated and described what 1 I now regardas the preferredembodiment of my invention, the construction is, of course, subject tomodifications without departing from the spirit and scope of minvention. I, therefore,

do not wish to restrict myself to the particular 1 form of constructionillustrated and described, but desire to avail myself of allmodifications that may fall within the scope of the appended claim.

Having thus described my invention, What I i claim and desire to secureby Letters Patent is: A message delivery device comprising handleportion comprising a, housing having a dry cell battery therein andmounting a switch con trolling current flow from said battery, ahandgrasping member extending downwardly from said housing, anelectricall conductive tubular member extending upwardly from saidhousing, and a single electrical conductor generally coextensive withand within said tubular member; a lamp mounted in the upper end of thetubular member and electrically engaged by the upper end of saidelectrical conductor; message-holding means comprising a pair ofupwardly diverging light-conveying rods, the adjacent lower ends ofwhich substantially meet immediately above said lamp, and amessage-carrying loop supported by the upper ends of said rods; andmeans connecting the handle portion and the messageholding meanscomprising a one-piece light-conveying block formed with intersectingseats arranged in Y-form and receptive of the upper end of the tubularmember and the lower ends of the light-conveying rods, said lamp beingdisposed at the intersection of said seats.
